* The existing interrupt mitigation code didn't mitigate anything - the per-packet TX/RX interrupts are still occuring. It's possible this worked for the AR5416 but not any later chipsets; I'll investigate and update as needed. * Set both the RX and TX threshold registers whilst I'm at it. This is verified to work on the AR9220 and AR9160. I'm leaving it off by default in case it's truely broken, but I need to have it enabled when doing 11n testing or interrupt loads exceed 10,000 interrupts/sec.
